讨论了 DP、TRIP 和 TWIP 钢中的马氏体相变和显微组织特征。为了获得更好的性能，基于对微观结构稳定性的理解，描述了控制 DP 和 TRIP 钢生产的细节。从热力学和动力学评估方面评估了TRIP钢中P对Al和/或Si的替代。计算了TRIP钢的最小快冷速率和最佳过时效温度和时间。通过与成分、应变和热处理的关系来评估堆垛层错及其对高锰钢相变的影响。
Martensite phase transformation and microstructure features in DP, TRIP and TWIP steels are discussed. For the obtaining of better properties, details in controlling the production of DP and TRIP steels are described based on the understanding of the stability of microstructures. Substitution of P for Al and/or Si in TRIP steel is evaluated from the aspects of thermodynamic and kinetic estimation. The minimum fast cooling rate and optimal over-aging temperature and time has been calculated for TRIP steel. Stack fault and its effect on phase transformation in high Mn steel are evaluated in the relationship with composition, strain, and heat treatment.
